[0031] The embodiments of the present application are described below in detail with reference to the accompanying drawings. In the drawings, the same or similar components are denoted by the same or similar reference numerals throughout. The embodiments described below are examples for explaining the present application and are not intended to be limiting of the present application.

[0032] Reference is made below to Figures 1-4 A clutch device 10 according to the embodiment of the present application is described below. The clutch device 10 includes a housing, a first transmission shaft 11, a second transmission shaft 12, a transmission assembly 13, and a driving member 14.

[0033] The first transmission shaft 11 and the second transmission shaft 12 are both accommodated in the housing. The first transmission shaft 11 is in power connection with a driving shaft, and the second transmission shaft 12 is in power connection with an electric drive axle. The transmission assembly 13 is accommodated in the housing and is sleeved on the outer circumferential wall of the first transmission shaft 11 and the second transmission shaft 12. A part of the transmission assembly 13 is in power connection with one of the first transmission shaft 11 and the second transmission shaft 12, and another part of the transmission assembly 13 is selectively in power connection with the other of the first transmission shaft 11 and the second transmission shaft 12. At least part of the outer circumferential wall of the transmission assembly 13 is formed with a cooperating part 131. The driving member 14 is connected with the housing, and the driving member 14 is selectively cooperated with the cooperating part 131 to drive the transmission assembly 13 to move axially and disconnect the transmission assembly 13 from the first transmission shaft 11 or the second transmission shaft 12.

[0034] At present, hybrid electric vehicles usually adopt engine and motor dual drive mode, in order to realize lower energy consumption and longer endurance of the whole vehicle, the control strategy is usually to drive in pure electric mode at low speed, and the rear electric drive axle is responsible for driving the wheels, when the battery power is insufficient or at high speed, switch to pure engine driving mode, at this time, the electric drive axle is closed, however, in the pure engine driving mode, after the electric drive axle is closed, the wheels may still drag the motor reducer system to idle, resulting in a large drag torque of the system, thereby causing energy loss.

[0035] To this end, the application provides a clutch device 10, which can disconnect the driving shaft from the electric drive axle through the transmission assembly 13, thereby reducing energy loss.

[0036] As shown in Figure 1 Specifically, the clutch device 10 can include a housing (not shown in the figure), a first transmission shaft 11, a second transmission shaft 12 and a transmission assembly 13, the first transmission shaft 11 and the second transmission shaft 12 can be accommodated inside the housing, and the first transmission shaft 11 can be power connected with the driving shaft, the second transmission shaft 12 can be power connected with the electric drive axle, the transmission assembly 13 can be accommodated in the housing, and the transmission assembly 13 can be sleeved on the outer peripheral wall of the first transmission shaft 11 and the second transmission shaft 12, wherein a part of the transmission assembly 13 can be power connected with one of the first transmission shaft 11 and the second transmission shaft 12, and another part of the transmission assembly 13 can be selectively power connected with the other of the first transmission shaft 11 and the second transmission shaft 12. It can be understood that a part of the transmission assembly 13 can be connected with the first transmission shaft 11, and another part of the transmission assembly 13 can be selectively power connected with the second transmission shaft 12, or a part of the transmission assembly 13 can be power connected with the second transmission shaft 12, and another part of the transmission assembly 13 can be selectively power connected with the first transmission shaft 11. Alternatively, the transmission assembly 13 and the first transmission shaft 11 or the second transmission shaft 12 can be power connected through key connection, that is, through spline connection, which can make the radial structure more compact and ensure that the clutch device 10 can be adapted to more vehicle models.

[0037] Further, at least part of the outer peripheral wall of the transmission assembly 13 can be formed with a matching portion 131, and the clutch device 10 can further include a driving member 14, which can be connected with the housing and can selectively match with the matching portion 131 to drive the transmission assembly 13 to move axially, thereby disconnecting the transmission assembly 13 from the first transmission shaft 11 or the second transmission shaft 12, and when the first transmission shaft 11 and the second transmission shaft 12 are disconnected, the drive shaft and the electric drive axle of the vehicle are also disconnected synchronously, thereby avoiding the wheels from driving the electric drive axle to idle through the drive shaft and reducing the loss of energy. In specific embodiments, the transmission assembly 13 can be connected with the second transmission shaft 12 through a spline, and the transmission assembly 13 can be selectively connected with the first transmission shaft 11. When the electric drive axle is closed, the driving member 14 can move towards the matching portion 131 and match with the matching portion 131, thereby moving the transmission assembly 13 relative to the first transmission shaft 11 and the second transmission shaft 12. During the movement, the transmission assembly 13 is always connected with the second transmission shaft 12 through the spline, and the transmission assembly 13 is disconnected from the first transmission shaft 11, thereby disconnecting the drive shaft from the electric drive axle, so as to realize the interruption of power.

[0038] Briefly, the clutch device 10 of the embodiments of the present application is provided with a transmission assembly 13 and a driving member 14. A part of the transmission assembly 13 can be connected with one of the first transmission shaft 11 and the second transmission shaft 12, and another part of the transmission assembly 13 can be selectively connected with the other of the first transmission shaft 11 and the second transmission shaft 12. The transmission assembly 13 is further formed with a matching portion 131, and the driving member 14 can drive the transmission assembly 13 to move axially by matching with the matching portion 131, thereby disconnecting the transmission assembly 13 from the first transmission shaft 11 or the second transmission shaft 12, and further disconnecting the drive shaft and the electric drive axle, so as to reduce the loss of energy.

[0039] As Figure 2As shown in the drawings, in some embodiments of the present application, the end of the matching part 131 in the axial direction can be formed with a stepped surface 1311, the outer peripheral wall of the matching part 131 can be formed with a matching groove 1312 recessed towards the inside of the matching part 131, the driving member 14 can selectively move towards the matching groove 1312, and the inner wall of the matching part 131 can extend in the circumferential direction to the stepped surface 1311, wherein the circumferential direction can be the circumferential direction of the transmission assembly 13. The driving member 14 can selectively move along the inner wall of the matching groove 1312 to the stepped surface 1311, and the driving member 14 and the stepped surface 1311 can abut in the axial direction, thereby driving the transmission assembly 13 to move in the axial direction. It should be noted that after the electric drive axle is closed, the driving shaft still drives the electric drive axle to rotate. When the driving member 14 moves towards the matching groove 1312 until the driving member 14 abuts against the inner wall of the matching groove 1312, the transmission assembly 13 moves in the axial direction due to the reaction force until the driving member 14 moves to the stepped surface 1311 and abuts against the stepped surface 1311, and the transmission assembly 13 is disconnected from the first transmission shaft 11, thereby achieving power interruption. By providing the above structure, the driving shaft and the electric drive axle can be quickly and efficiently disconnected, thereby ensuring the reliability of the clutch device 10.

[0040] As shown in the drawings, Figure 2 In some embodiments of the present application, the outer peripheral wall of the matching part 131 is formed with a guide surface 1313, which can extend obliquely towards the bottom wall of the matching groove 1312. When the driving member 14 moves towards the matching groove 1312, the guide surface 1313 can guide the driving member 14, allowing the driving member 14 to move along the guide surface 1313 to the bottom wall of the matching groove 1312 and abut against the side wall of the matching groove 1312. This avoids wear between the driving member 14 and the matching part 131, allowing the driving member 14 to move more quickly into the matching groove 1312 and improving the reliability of the driving member 14.

[0041] As shown in the drawings, Figure 3 and Figure 4 In some embodiments of the present application, the driving member 14 can include a valve body 141 and a bearing 142. The valve body 141 can be connected to the housing, and the bearing 142 can be sleeved on the output end of the valve body 141. The valve body 141 can be used to drive the bearing 142 to move towards the matching groove 1312. In some embodiments, the valve body 141 can be configured as an electromagnetic valve. The bearing 142 can include an inner shaft and an outer shaft. The inner shaft can be connected to the valve body 141, and the outer shaft can be selectively connected to the inner wall of the matching groove 1312. When the bearing 142 moves to the bottom wall of the matching groove 1312, the outer shaft can be connected to the side wall of the matching groove 1312. When the matching groove 1312 rotates, the outer shaft can rotate synchronously, thereby avoiding wear between the bearing 142 and the matching groove 1312 and improving the service life of the transmission assembly 13.

[0042] AsFigure 1 , Figure 3 and Figure 4 As shown, in some embodiments of this application, the clutch device 10 may further include an elastic element 15. The elastic element 15 may be sleeved on the outer periphery of the transmission assembly 13, and one end of the elastic element 15 along the axial direction may abut against the mating part 131, and the other end of the elastic element 15 along the axial direction may abut against the housing. The elastic element 15 can play a restoring role. When the electric drive is opened, the valve body 141 drives the bearing 142 to disengage from the step surface 1311. The elastic element 15 can drive the transmission assembly 13 to move so that the transmission assembly 13 is connected to the first transmission shaft 11, thereby connecting the electric drive bridge and the drive shaft to achieve power transmission.

[0043] like Figure 3 and Figure 4 As shown, in some embodiments of this application, a first transmission part 111 may be formed on the outer peripheral wall of the first transmission shaft 11, and the first transmission part 111 may extend circumferentially. A second transmission part 132 may be formed on the inner peripheral wall of the transmission assembly 13, and the second transmission part 132 may extend circumferentially. The second transmission part 132 may be correspondingly arranged with the first transmission part 111, and the second transmission part 132 may be dynamically connected to the first transmission part 111 to realize the connection between the transmission assembly 13 and the first transmission shaft 11. When the transmission assembly 13 moves axially, the first transmission part 111 and the second transmission part 132 will move accordingly. The transmission assembly 13 moves and separates, thereby disconnecting the transmission assembly 13 from the first transmission shaft 11. In some embodiments, the first transmission part 111 can be constructed as an external spline, and the second transmission part 132 can be constructed as an internal spline. The first transmission part 111 and the second transmission part 132 can be connected by a spline. Further, the first transmission part 111 can be constructed as a plurality of parts spaced apart along the axial direction, and the second transmission part 132 can be constructed as a plurality of parts corresponding one-to-one with the plurality of first transmission parts 111. By providing a plurality of first transmission parts 111 and a plurality of second transmission parts 132, the power transmission can be made more reliable.

[0044] like Figure 3 and Figure 4 As shown, in some embodiments of this application, a limiting member 112 can be formed on the outer peripheral wall of the first transmission shaft 11. The limiting member 112 can be arranged circumferentially. When the first transmission part 111 and the second transmission part 132 are poweredly connected, the limiting member 112 can abut against the end of the transmission assembly 13, thereby limiting the distance that the transmission assembly 13 can move axially. Specifically, when the electric drive is turned on, the valve body 141 drives the bearing 142 to disengage from the step surface 1311. The elastic member 15 can drive the transmission assembly 13 to move until the end of the transmission assembly 13 abuts against the limiting member 112. At this time, the transmission assembly 13 stops moving axially. At this time, the first transmission part 111 and the second transmission part 132 can be correspondingly arranged and poweredly connected, thereby realizing the transmission of power.

[0045] As Figure 1 , Figure 3 and Figure 4 shown, in some embodiments of the present application, the outer peripheral wall of the transmission assembly 13 can be provided with a first detection piece 133, and the clutch device 10 can further include a second detection piece 16, the second detection piece 16 can be connected with the housing, and the second detection piece 16 can be used to detect the position of the first detection piece 133, in specific embodiments, the first detection piece 133 can be configured as a magnetic ring, and the second detection piece 16 can be configured as a sensor, the second detection piece 16 can judge the current connection relationship between the transmission assembly 13 and the first transmission shaft 11 by detecting the position of the first detection piece 133, that is, the transmission assembly 13 is connected or disconnected with the first transmission shaft 11, by setting the first detection piece 133 and the second detection piece 16, the position of the transmission assembly 13 can be quickly judged, and it is beneficial to monitor whether the transmission and clutch device 10 is working normally.
